Question

How is the brain informed that a receptor is adapting to a stimulus?

Answer 1

The fullness of the generator potential or the occurrence release of the sensory fiber decreases. In addition, receptors re specialized cells or specialized endings of afferent neurons-OH which is not dendrites. The three major components of sensory systems are receptors which is sensitive to changes in environment, neural pathway which carry information from receptor to brain and brain which interprets sensory information. 

Answer 2

When the receiver is adapting to a stimulus, the receiver decreases its polarization. This causes a decrease in frequencies that travel to the brain, informing the brain that the receptor is in the process of adapting.

Step-by-step explanation:

Each neurotransmitter is programmed to respond to certain stimuli. To do so, they are endowed with receptors that recognize signaling molecules and send rapid responses to the brain. These molecules can be proteins, amino acids, hormones and various other substances. The moment it receives a stimulus, the receptors undergo a rapid adaptation period, at which point the receptor decreases its depolarization. This causes the frequency of signals that this receptor sends to the brain to be decreased, signaling to the brain that adaptation is taking place.
